Abstract
We present a method for the deterministic generation of all the electronic Bell states of two trapped ions. It involves the combination of a purely di spersive with a resonant laser excitation of vibronic transitions of the io ns. In contrast to other methods presented up to now, our proposal does not require differential laser addressing of the individual ions and may be ea sily implemented with present available techniques. It is further shown tha t this excitation scheme is highly adequate for the complete determination of the motional state of the ions. [S1050-2947(99)50604-5].
